Hi Dale: I also ordered the Proset with my K3 and it arrived with the proper connectors to plug it into the front or rear.
The headphone portion of the cable has a stereo 1/8" plug with a 1/8" to 1/4" adapter. The microphone portion of the cable has a mono 1/8" plug with an adapter cable that converts it to the round front panel microphone connector and also provides a means to plug in a footswitch. I presently have both the microphone and headphone cables plugged into the rear MIC and PHONES sockets. I am not using either adapter. If your Proset didn't arrive with these connectors and adapters you should contact Elecraft so that they can investigate. Maybe Heil sent them some Prosets with an incorrect plug arrangement. I'm sure Elecraft contracted with Heil to provide the Proset with an arrangement that would work both front and rear. 73, Mike K2MK Dale Harding K7DNH Fri, 26 Jun 2009 19:16:08 -0700 Newbie question - I dont want to take the chance to fry something. I want to start using the Heil Proset-K2 I ordered with the K3 - but a bit unsure of exactly how to set it up. THe instructions that came with it are mostly for installing the necessary kit into the K2. I searched thr reflector for the setting to use and came up with opposing views... the majority stated if using the front panel use the following: Use the adapter supplied and plug in both connectors and then into the k3 front panel, FP Low - with bias on, Vox On, VOx gain = 50, antivox=00 To use the rear panel - do not use the adapter " and plug the connectors into the repar panel jacks - well - exactly which ones? The only two that the large one will fit is the paddle and the key. Apprecaite your help folks, Dale K7DNH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
